There are multiple frontends for ecasound. Ecaenvelopter is just meant to make envelopes. it can't do any of the other many functions that ecasound has. Some things that may come closer are tkeca ( http://tkeca.sourceforge.net/ ) and visecas ( http://visecas.sourceforge.net/ ). I have not tried them though.

Gimme my audacity, though.

Audacity and ecasound have very different design philosophies and uses. Obviously, you're not going to use ecasound for something that you can do with 2 clicks in Audacity. But Audacity is purely an audio file editor (and a good one too), whereas ecasound can be used for routing streams, live effect processing and more.
